WFC design session v26: best candidate (Q=78.9, 69.8kHz)

Sweep: screen-guided: live [Water purity, Temperature], refined score 0.742

Cell: 18mm rod in 34.0mm tube × 25mm, 8 cell(s) parallel → C_eff = 1.53nF, bulk water R = 127048Ω. Water/electrodes (Randles): 0.1ppm Na+ @ 1°C, surface ×0.25 → λ_D 227nm, C_dl 6.3µF, cell series R 17.5Ω, displacement current 98.8%, breakdown margin ×566. Vapor-film discharge (CGDE onset, 947V across 0.1mm film): regime townsend-avalanche, film Paschen 719V, 378 Td. Chokes: 2 × 0.0017H (180 turns, AWG 18, 21m wire, AC R 0.7Ω each). At resonance f_r = 69.82kHz: Xl = 1492Ω, Xc = 1492Ω, tank Q = 78.9, coil Q = 1081.4. Cell voltage 947V from 12V drive (×78.9), series current 635.1mA. All constraints satisfied (current <1A, band, wire length). Score 0.742.
